Ordinary silicon, the material that has dominated the semiconductor industry for decades, could also make a very promising host material for quantum bits in a future quantum computer. So say researchers at the Delft University of Technology in the Netherlands and the University of Wisconsin at Madison in the US, who have found that electrically controlled silicon-based qubits are 100 times more robust than those based on the compound semiconductor gallium arsenide…..
